So how do big beasts fare… …beneath the waves. Down here, water’s buoyancy helped support
nature’s heavy weights which is why this is the domain of the
most enormous animal ever to have existed. The 150 tonne blue whale outdoes even the biggest dinosaurs for size. its tongue alone weighs as much as its
largest land rival, the elephant. its heart is almost as big as a golf
buggy. its major artery is as wide as a human
head. and it’s thought they’re still growing. As long as the blue whale has enough
food, this species may just keep on getting bigger.

What's crazy is that it's a mammal that evolved from Pakicetus (a dog hipo looking thing) only fifteen million years ago too; such a dramatic transformation in such a short time is in the evolutionary scheme of things is absurd, It's almost recognizable from its closest ancestor. Anyway, So it's basically it's a giant dog hippo.
